The Lowdown
Alright, Rusty here again. Let's run it down in feet and degrees.
The water here at Jaconé is about 72°, which is normal for the season.
The first real standout is Wednesday July 15th morning. The swell is running 6ft from the SSE, with a 10-second period that gives it some real grunt. The combined energy is 715 (moderate), so there’s plenty of power. The wind is a light offshore from the NE, keeping the faces clean. Expect very good surf. This is the one to get on.
Thursday and Friday mornings are still fun, with 5ft and 3ft respectively, still from the SE, and that same light offshore NE wind. It’s a bit smaller, but still clean.
Then we get another highlight: Sunday July 19th morning. The swell pops back up to 6ft from the ENE, with an 8-second period, and the combined energy is 540 (moderate). The wind is offshore from the NNE, light breeze. Expect very good surf conditions. This is a solid day.
The middle of the week goes quiet. Tuesday and Wednesday are small and weak, with energy dropping under 100. Just surfable, but nothing special.
But Thursday July 23rd morning is a sneaky one. The swell is only 4ft from the ENE, but the wind is glassy – dead calm. Combined energy is 237 (moderate). That’s going to be butter-smooth and fun.
Into the second week, Friday July 24th morning brings a shift. Swell is 3ft but swings to the S with a long 11-second period, and the wind is offshore from the NNE. Combined energy is 297 (moderate). That’s a groundswell, so it’ll have extra push and shape, though it might be a bit straight for some breaks.
The big one to circle is Tuesday July 28th morning. This is about a week and a half out, so it’s a potential, but it looks good. Swell is 4ft from the SSW, with a very long 12-second period, and the wind is offshore from the ENE. Combined energy is 813 (moderate-to-strong). Expect very good surf conditions. This is a proper groundswell with clean, powerful waves.
Wednesday July 29th morning is also strong. Swell is 5ft from the S, 12-second period, with a moderate offshore NE wind. Combined energy is 757 (moderate). Clean, punchy, well-shaped.
The last few days on the 25th look messy with onshore wind and small swell, so that’s the end of the run.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
